which element has the electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d8
Answer:
Darmstadtium
Explanation:
An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ has 110 electrons in its electron shells.
Since the element is a neutral atom, this number is also equal to its atomic number. Therefore, its atomic number is 110.
The element in the period table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transittion metal. It also belong to period 7 in the Periodic table of elements.
The element that has the electron configuration is Darmstadtium.
Electronic configuration:Since An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ contains 110 electrons in its electron shells.
Also, the element should be a neutral atom, this number should also equal to its atomic number. Therefore, its atomic number is 110.
The element in the periodic table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transition metal.

The valence electrons are those found in the highest energy ____ and ___ orbitals
^Please help ASAP I’ll mark you as brainlister FILL in the blank
The outmost free electron which is present in the outer shell is called valency. The number of elements joining together to form the compound also depends on the valency.
Each electron has revolved around the nucleus and that path is considered as orbit. The orbit is as follows:-
SPDFThe free electrons are usually lie in the outmost shell.
Hence according to the question, the correct option is S and P orbit.

explain the relationships that are present between the frequency, wavelength, and amplitude of a wave in 3 to 5 sentences.
Answer:
Wavelength refers to the length of a wave from one peak to the next. The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak. Wavelength is directly related to the frequency of a given wave form.
Which pair of symbols represents nuclei with the same number of neutrons?
A. 56 Co and 580
B. 57Co and 58Ni
c. 57Fe and 58 Ni
D. 57Mn and 57Fe
Answer:
B
Explanation:
Mass number = number of neutrons + number of protons
Atomic number is the number of protons in the nucleus.
58Ni : 58 is the number of neutrons + number of protons
atomic number of Ni is 28. Thus, 58 -28 = 30 neutrons
57Co ; 57 is the number of neutrons + number of protons
number of Co is 27. Thus, 57 – 27 = 30 neutrons

At what temperature does water boil at 101kPa?
Answer:
100°C
Explanation:
A liquid boils when the vapour pressure is the same as the atmospheric pressure. At 101kPa or 1 atm, water boils at the well known number of 100°C. If the pressure is different, you will have to use the Clausius Clapeyron Equation.

2. Calculate the density of a rock that has a mass of 21.58 grams and causes the water in a
graduated cylinder to rise from 20.0yl to 25.4 ml.
Answer:
4.00 g/mL
Explanation:
Density is mass divided by volume (g/mL).
Mass of rock = 21.58
Volume of rock = 25.4 - 20.0 = 5.4mL
Density of rock = 21.58g / 5.4mL = 3.99629 g/mL
Round to the lowest number of significant figures which is three = 4.00 g/mL
